Yelp announced today that it surpassed 100 million unique vistors on its site in January, marking the first time in Yelp history it has had that many uniques in a month.

“That’s an all-time high for traffic to the desktop and mobile site and a clear indication that people are looking for local businesses and finding them on Yelp,” said CEO Jeremy Stoppelman in a blog post. “While that number is huge, it doesn’t even include the 9.4 million unique mobile devices that used the Yelp mobile app in January alone.”

“Even more staggering than 100 million unique visitors using Yelp.com in January are the millions of contributions Yelpers made to the community in the same time frame,” he added. “The 4.6 million calls and 5.7 million directions generated through the Yelp mobile app and nearly 2 million bookmarks created by Yelpers are the connection between searching for a specific local business and making a spending decision.”

According to Stoppelman, who cites a recent survey, business owners on Yelp report that the average customer across all categories spends $101.59 in their first visit.
